Description

Picture processing method and related device

Technical Field

The present application relates to the field of information processing technologies, and in particular, to a picture processing method and a related apparatus.

Background

At present, information including shooting date, aperture, shutter, focal length, contrast, saturation, GPS positioning, thumbnail and the like, namely exchangeable picture file format (Exif) information, can be collected by smart phones and digital cameras in the shooting process. The Exif information is set specifically for a photograph of a digital camera, and can record attribute information and shot data of the data photograph. The Exif information may be attached to a file such as JPEG, TIFF, RIFF, or the like, to which parameter information related to the content of the digital camera shooting information and thumbnail images or image processing is added.

The current Exif information holds privacy information of a part of users, for example, GPS location information is carried when picture data is sent, and the like, so that an acquirer can deduce a private address of the user based on the GPS location information. For example, when a picture of the other party is obtained from a social channel, the obtaining person may inquire the GPS location information of the picture in the picture detail information. Then, the acquirer can view the shooting position of the picture on the map by the GPS position information. This causes personal privacy data of the photo holder to be revealed.

Detailed Description

The technical solution in the embodiments of the present application will be described in detail and removed with reference to the accompanying drawings. In the description of the embodiments herein, "/" means "or" unless otherwise specified, for example, a/B may mean a or B; "and/or" in the text is only an association relationship describing an associated object, and means that three relationships may exist, for example, a and/or B may mean: three cases of a alone, a and B both, and B alone exist, and in addition, "a plurality" means two or more than two in the description of the embodiments of the present application.

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as implying or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of embodiments of the application, unless stated otherwise, "plurality" means two or more.

The following describes the picture file format involved in the embodiments of the present application.

Referring to fig. 1, fig. 1 is a schematic diagram of a picture file format according to an embodiment of the present disclosure. As shown in fig. 1, the contents of the picture file all start at the start of image (SOI) flag and end at the end of image (EOI) flag. Wherein, the image start mark is a binary value of "0 xFDD 8", and the image end mark is "0 xFFDD 9". The picture file includes exchangeable image file format (Exif) data and main image data. Where the Exif data may start with the application 1(APP1) flag, the APP1 flag being a binary value "0 xFFE 1". The Exif data may include main image Exif information, thumbnail Exif information, and thumbnails. The main image Exif information is used to describe additional information of the main image data (e.g., information of photographing date, aperture, shutter, focal length, contrast, saturation, GPS position, etc.). The thumbnail Exif information is used to describe additional information of the thumbnail (e.g., the size of the thumbnail, the compression method of the thumbnail, etc.)

Wherein each parameter in the Exif data is tagged with a different tag. Analyzing the tag value in the Exif data, the storage location of each parameter in the Exif data can be determined. For example, the labels associated with GPS location information may be as shown in table 1 below:

TABLE 1

As can be seen from table 1 above, in the GPS location information, the tag value corresponding to the GPS version is "0", the tag value corresponding to the north-south latitude of the GPS is "1", the tag value corresponding to the GPS latitude is "2", the tag value corresponding to the east-west longitude of the GPS is "3", the tag value corresponding to the GPS longitude value is "4", the tag value corresponding to the GPS altitude reference value is "5", the tag value corresponding to the GPS altitude is "6", the tag value corresponding to the GPS timestamp is "7", the tag value corresponding to the satellite measured by the GPS is "8", the tag value corresponding to the GPS receiver state is "9", the tag value corresponding to the GPS measurement mode is "10", the tag value corresponding to the GPS precision is "11", the tag value corresponding to the GPS speed unit is "12", the tag value corresponding to the GPS receiver speed is "13", the tag value corresponding to the GPS mobile azimuth reference is "14", and the tag value corresponding to the GPS mobile azimuth is "15". The examples shown in table 1 above are merely illustrative of the present application and should not be construed as limiting.

The following describes a process of reading an original picture by an application program on an electronic device in the related art.

Referring to fig. 2, fig. 2 shows a flow of reading an original picture by an application in the related art of the present application. As shown in fig. 2, at present, the process of reading picture data by an application program on an electronic device such as a mobile phone or a tablet may be as follows:

s201, after receiving the task of loading and displaying the picture, the upper layer application (e.g., the wechat application) may create a picture reading request and issue the picture reading request to the picture obtaining module.

The picture reading request may include information such as a picture address, an operation type, and a conversion operation.

S202, after receiving the picture obtaining request, the picture obtaining module may determine whether the picture exists in the cache, and if the picture exists in the cache. The image acquisition module can read the data of the image from the cache and report the data to the upper application so as to display the image on the target interface layout.

S203, when the cache does not contain the data of the picture, the picture obtaining module may identify the loading path of the picture according to the picture address in the picture reading request.

Wherein each resource (e.g., picture, video clip, etc.) available to the electronic device can be represented by a Uniform Resource Identifier (URI). A URI may generally consist of three parts: the naming mechanism (scheme) for accessing the resource, the host name (hostname) for storing the resource, and the name (path) of the resource itself. The picture retrieval module may convert the URI of the picture into a storage path of the picture.

The picture acquisition module can judge the loading way of the picture according to the naming mechanism of the access resource in the URI of the picture. For example, when scheme is "content://" in the URI of the picture, the loaded picture is a picture stored locally on the electronic device. When scheme in the URI of the picture is http://, the loaded picture is a web picture.

Illustratively, the URI of all picture folders on the electronic device may be "content:// media/external", wherein the URI of picture A in all pictures may be "content:// media/external/images/media/212304". The picture obtaining module may convert the URI of the picture a into a storage path of the picture, where the storage path of the picture a may be "file: v/storage/organized/0/Android/data/com.zn _ android.zn/cache/PostPicture/201905193015. jpg ". The above examples are merely illustrative of the present application and should not be construed as limiting.

S204, the scheduling module can enqueue the picture acquisition tasks and execute the tasks according to the enqueue sequence.

The scheduling module can achieve enqueue, execution, completion, cancellation, suspension and the like of image acquisition. The scheduling module can realize the switching and execution of the service logic in different threads, and can also be responsible for managing thread pools, downloading, decoding, caching and the like.

S205, the scheduling module may determine whether the picture acquiring task is successfully executed, and if so, execute step S206, and the scheduling module may call the picture processing module to process the stored picture.

Because the picture information stored in the bottom layer is subject to the conversion of coding and decoding because of the problem of data format, the picture information can become a common picture file. The picture processing module can perform processing operations such as decoding, reversing, cropping and the like on the picture.

If the scheduling module determines that the enqueued picture acquisition task fails to be executed, the scheduling module may feed back the picture acquisition failure to the upper layer application, and end the picture acquisition process.

S207, the picture processing module may determine whether the picture processing is successful, if so, execute step S208, and the picture processing module may call the cache module to store the processed (for example, decoding, converting, and other processing operations) picture in the cache, and return a call interface of the picture in the cache to the upper layer application.

And S209, the upper layer application can acquire the picture from the cache according to the calling interface returned by the cache module.

After the picture is acquired, the upper layer application can display the picture on the target application layout of the display screen, and can upload the picture to a server or send the picture to equipment of a contact person.

In other related technologies, some applications on the electronic device may also separately obtain Exif data of the picture. For example, in order for a gallery application on an electronic device to classify pictures according to their shooting addresses, the gallery application may obtain GPS location information and thumbnails of the pictures from the Exif data of the pictures. After the gallery application acquires the GPS position information and the thumbnails of the pictures, the gallery application may classify the pictures according to the GPS position information of the pictures, and display the thumbnails corresponding to the pictures of which the GPS position information belongs to the same region in the same display area of the gallery application interface.

For another example, in order for the gallery application to classify the pictures according to their shooting times, the gallery application may also obtain the shooting times and thumbnails of the pictures from the Exif data of the pictures. After the gallery application obtains the shooting time and the thumbnails of the pictures, the gallery application can classify the pictures according to the shooting time of the pictures, and the thumbnails corresponding to the pictures with the shooting time belonging to the same time period are displayed in the same display area of the gallery application interface.

For example, as shown in fig. 3, when the camera application has an authority to acquire GPS location information of the electronic device, the camera application may acquire the GPS location information of the electronic device at the time of taking a picture and store the GPS location information in a picture file of the taken picture. Wherein the GPS location information may be stored in Exif data of the picture file. When the gallery application needs to obtain the GPS location information of the picture, the gallery application may obtain the GPS location information of the picture from the Exif data in the picture file.

If the gallery application needs to classify the pictures according to the GPS position information of the pictures, the gallery application can also acquire the thumbnails of the picture files from the pictures. After the thumbnail and the GPS location information of the picture file are acquired, the gallery application may determine an address name (e.g., shenzhen city) corresponding to the GPS location information from the map, and divide the picture file into categories corresponding to the address name. When the electronic device opens the category corresponding to the address name in the gallery application in response to an operation by the user, the electronic device may display the thumbnail of the picture file in the category corresponding to the address name.

Illustratively, as shown in FIG. 4A, the electronic device 100 displays a gallery interface 410. One or more folders may be included in the gallery interface 410, among other things. Wherein the one or more folders are distinguished by address name. For example, the address names of the one or more folders may include Guangzhou, Shenzhen, Wuhan, Shanghai, Beijing, Zhuhai, and so on. The address name of folder 411 can be "Shenzhen City". That is, the shooting addresses representing the pictures in the folder 411 are all in "Shenzhen City".

The electronic device may receive an input operation for the folder 411 by a user, and in response to the input operation, the electronic device may display a folder interface 420 as shown in fig. 4B. As shown in fig. 4B, the folder interface 420 displays thumbnails corresponding to one or more pictures with shooting addresses in "shenzhen city".

Through the related technology, some applications with the photo reading authority can directly send the photo original image data to the contact person or upload the photo original image data to the server. The photo original image data carries corresponding Exif data. The Exif data may include shooting location information (e.g., GPS positioning information), shooting time, shooting device model, shooting mode, portrait mood information, and the like. The information does not affect the imaging and display effect of the picture, but private data of the person is exposed. For example, when the electronic device sends artwork using WeChat, a real picture file is sent out together with Exif data, causing leakage of user privacy data.

Some applications can also read Exif data of the picture independently, and after the applications read the Exif data of the picture independently, the applications also have the risk of revealing privacy of the user.

Therefore, the application provides a picture processing method, a user can set the authority of an application program for accessing the private information in the Exif data on the electronic device, and when a certain application does not have the authority for accessing the Exif data of a picture, the electronic device can dynamically delete the private information (such as GPS (global positioning system) position information, picture shooting time, picture shooting machine type and the like) in the Exif data in the process that the application acquires picture original pictures or acquires the Exif data independently. Therefore, the electronic equipment can dynamically delete the privacy information in the Exif data when the picture data is read or the Exif data in the picture data is read without changing the picture data stored in the mobile phone, and the user privacy is protected.

An electronic device 100 provided in the present application is described below.

Fig. 5 shows a schematic structural diagram of the electronic device 100.

When the Exif data acquiring module 604 acquires the whole Exif data in the picture file, the Exif data acquiring module 604 may delete the private information in the acquired Exif data, and report the Exif data with the private information deleted to the application B. When the Exif data acquiring module 604 needs to acquire information 1 (e.g., GPS location information) in the Exif data, the Exif data acquiring module 604 may determine whether the information 1 is private information, and if so, the Exif data acquiring module 604 may return a rejection instruction to the application B, where the rejection instruction is used to indicate that the application B has no right to acquire the information 1.

3. When an application C (e.g., an application such as a QQ) needs to obtain a thumbnail of a picture file, the Exif data optimization module 605 may determine whether the application C has permission to access private information in the picture file. If the application C does not have permission to access the private information in the picture file, the Exif data optimization module 605 may call the thumbnail acquisition module 606 to acquire the thumbnail data and the thumbnail Exif information, filter the private information in the thumbnail Exif information, and provide an interface for the application C to call the thumbnail data and the thumbnail Exif information after filtering the private information.

In a possible implementation manner, the Exif data optimization module 605 may determine whether the application C has permission to access the thumbnail in the picture folder, and if the application C does not have permission to access the thumbnail, the Exif data optimization module 606 may instruct the thumbnail obtaining module 606 to reject the thumbnail obtaining request of the application C.

The location functionality control can be used to send the current location information of the electronic device 100 to the contact's device. The red packet function control and the transfer function control can be used for triggering electronic transfer to an account of a contact person. The voice input functionality control can be used to trigger the collection of a user's voice and transmission to a contact's device. The favorite functionality control can be used to open files (e.g., pictures, documents, music, videos, etc.) that the user has favorite on the WeChat application.

The electronic device 100 receives an input operation (e.g., a single click) by the user with respect to the album function control 936, and in response to the input operation, the electronic device 100 may display a picture selection interface 940 as shown in fig. 9E.

As shown in fig. 9E, the picture selection interface 940 may include thumbnails of one or more pictures. Wherein each thumbnail may have a mark displayed thereon. The flag may be used to indicate whether the user selected the picture corresponding to the thumbnail. For example, the picture corresponding to the thumbnail 941 may be the picture 811 in fig. 8A, and the thumbnail 941 has a mark 942 displayed thereon, where the mark 942 is currently in an unselected state to indicate that the picture corresponding to the thumbnail 941 is unselected by the user. The picture selection interface 940 may include artwork selection controls 943, and the artwork selection controls 943 may be used by the electronic device 100 to send a picture selected by a user to a device of a contact without compression. The original function control 943 is currently in an off state, which is used to indicate that the electronic device 100 is currently compressing the picture to be sent selected by the user.

The electronic apparatus 100 can receive an input operation (e.g., a single click) by the user on the thumbnail 941, and in response to the input operation, the mark 942 that the electronic apparatus 100 can have on the thumbnail 941 can be switched to the selected state. The mark 942, when in a selected state, can be used to indicate that the picture corresponding to the thumbnail 941 has been selected by the user. The electronic apparatus 100 may receive an input operation (e.g., a single click) by the user on the original function control 943, and in response to the input operation, the electronic apparatus 100 may switch the original function control to the on state.

As shown in fig. 9F, the user has selected the picture corresponding to thumbnail 941. The mark 942 on the thumbnail image 941 is in a selected state. The original function control 943 is in an open state. After the user selects thumbnail 941, electronic device 100 may display send control 944 on picture selection interface 940.

The electronic device 100 may receive an input operation (e.g., a single click) by a user with respect to the sending control 944, in response to which the electronic device 100 may determine whether the wechat application has authority to access the private information of the picture (e.g., shooting address information, shooting time, shooting device model, shooting mode, etc.), and if the wechat application does not have authority to access the private information of the picture, the electronic device 100 may filter (may also be referred to as delete) the private information (e.g., shooting address information, shooting time, shooting device model, shooting mode, etc.) in the Exif data of the picture before the wechat application acquires the picture corresponding to the thumbnail 941.

When encoding and decoding the picture corresponding to the thumbnail 941, the electronic device 100 may filter out privacy information in Exif data of the picture, and store the picture data with the filtered (also referred to as deleted) privacy information in a cache for the wechat application to read. In another possible implementation manner, after encoding and decoding the picture corresponding to the thumbnail 941, the electronic device 100 may store the encoded and decoded picture data in a cache, then filter (may also be referred to as delete) the privacy information in the Exif data of the picture data in the cache, and then return the picture data with the filtered privacy information to the wechat application. In this way, the electronic device 100 may not change the original picture data stored in the mobile phone itself, and dynamically delete the privacy information in the picture data when reading the picture data, thereby protecting the privacy of the user. For specific implementation, reference may be made to the foregoing embodiment shown in fig. 6, which is not described herein again.

After filtering out the privacy information (e.g., shooting address information, shooting time, shooting device model, shooting mode, etc.) in the picture selected by the user, the electronic device 100 may send the picture with the filtered privacy information to the device of the contact.

In one possible implementation, the electronic device 100 may directly send the picture of the filtered privacy information to a server of the WeChat application, and then the server sends the picture of the filtered privacy information to a device (e.g., the electronic device 101) of the contact. In another possible implementation, the electronic device 100 may send a picture of the filtered private information to a file server of the WeChat application. The electronic device 100 then sends the link to the picture to the device of the contact (e.g., electronic device 101) via the messaging server of the WeChat application. After the device of the contact (e.g., the electronic device 101) acquires the link of the picture through the communication server of the wechat application, the picture can be downloaded from the server according to the link of the picture.

As shown in fig. 9G, after the electronic device 100 sends the picture corresponding to the thumbnail 941 to the contact (e.g., "MAC") through the wechat application, the thumbnail 951 may be displayed in the chat interface 930. The thumbnail 951 and the thumbnail 941 in fig. 9E are from the same picture.

After the device of the contact (e.g., electronic device 101) receives the picture sent by electronic device 100 through the WeChat application, the device of the contact may be stored locally. The user may view the picture and the picture related information in a gallery on the contact's device. Wherein the privacy information (e.g., shooting address information, shooting mode, shooting time, camera type, etc.) in the picture acquired by the contact's device (electronic device 101) has been filtered. That is, the user cannot view the private information of the picture from the electronic device 101.

Illustratively, as shown in FIG. 10A, the device of the contact may be an electronic device 101. A chat interface 1010 with a WeChat application is displayed on the electronic device 101.

The picture 1021 is sent to the electronic device 101 by the electronic device 100 through the WeChat application. The save control 1022 may be used to trigger the electronic device 101 to save the picture 1021 to a local folder (e.g., the storage path of the picture 1021 may be "internal storage/DCIM/weixin/IMG _20190715_ 155430").

After the electronic device 101 stores the picture 1021 locally, the user can view the picture 1021 and the related information of the picture 1021 in the gallery application.

Illustratively, as shown in FIG. 10C, the electronic device 101 is displayed with a gallery application interface 1030. One or more albums (e.g., all photo albums, video albums, camera albums, screen shot catalog albums, WeChat album 1031, microblog albums, etc.) may be displayed in the gallery application interface 1030. The picture 1021 is stored in the wechat album 1031.

The electronic device 101 may receive an input operation (e.g., a single click) by the user with respect to the wechat album application 1031, and in response to the input operation, the electronic device 101 may display a wechat album interface 1040 as shown in fig. 10D.

As shown in fig. 10D, the wechat album interface 1040 displays thumbnails including one or more pictures (e.g., the thumbnail 1041 of the picture 1021, etc.).

The electronic device 101 may receive an input operation (e.g., a single click) by the user for the thumbnail 1041, and in response to the input operation, the electronic device 101 may display a picture browsing interface 1050 as shown in fig. 10E.

As shown in fig. 10F, the detailed information of the picture 1021 is displayed in the picture detailed information window 1060. The detailed information of the picture 1021 may include a storage name, a shooting parameter, a storage path, and the like. For example, the storage name of the picture 1021 may be "IMG _20190715_ 155430". The shooting parameters of the picture 811 may be "sensitivity (ISO) 50, shutter speed 1/3279s, focus mode auto focus (AF-a), white balance (AWB) on state, exposure compensation (EV) 0, aperture (F) 1.8, flash auto mode, focal length 27mm (equivalent 35mm film focal length), and so on. The storage path of the picture 1021 is "internal storage/DCIM/Camera/IMG _20190715_ 155430". Wherein the electronic device 101 cannot acquire the privacy information (e.g., shooting address information, shooting mode, shooting time, camera type, etc.) of the picture 1021. The above examples are merely illustrative of the present application and should not be construed as limiting.

In some application scenarios, an application on the electronic device 100 may separately obtain Exif data for a picture. When an application on the electronic device 100 requests to acquire the Exif data of the photo, the electronic device 100 may determine whether the application has the right to acquire the Exif data of the euro-gram. If the application does not have permission to access the private information in the picture file on the electronic device 100, the electronic device 100 may filter the private information in the Exif data before the application acquires the Exif data of the picture. In this way, the electronic device 100 may not change the original picture data stored in the mobile phone itself, and when the application reads the Exif data, the privacy information in the picture data is dynamically deleted, thereby protecting the privacy of the user.

In some application scenarios, an application on the electronic device 100 may separately obtain thumbnails of pictures and thumbnail Exif information. When an application on the electronic device 100 requests to acquire a thumbnail of a picture and thumbnail Exif information, the electronic device 100 may determine whether the application has the right to acquire Exif data of an european image. If the application does not have permission to access the thumbnail and the thumbnail Exif information in the picture file on the electronic device 100, the electronic device 100 may reject the request of the application. In this way, the electronic device 100 may not change the original picture data stored in the mobile phone itself, and when an unauthorized application requests to acquire the thumbnail and the thumbnail Exif information, the request is rejected, thereby protecting the privacy of the user.

In some application scenarios, the electronic device 100 may save the picture to a cloud server and bind with the cloud account of user a. When the user a needs to share the picture on the cloud account with the user B, the electronic device 100 may send the acquisition address of the picture (or a file including multiple pictures) selected by the user a on the cloud server to the device of the user B (e.g., the electronic device 101) in a specified manner. After receiving the acquisition address of the picture, the device (e.g., the electronic device 101) of the user B may acquire a thumbnail of the picture from the cloud server and display the thumbnail, or receive an operation of the user B to download the picture shared by the user a from the cloud server. The cloud server may encrypt the private information in the Exif data of the picture, and then send the picture with the encrypted private information to a device (e.g., the electronic device 101) of the user B. Therefore, when the electronic device 100 shares the picture with other devices, the other devices are prevented from acquiring the privacy information in the picture, and the privacy of the user is protected.

Illustratively, as shown in FIG. 11A, electronic device 100 displays a gallery interface 1110. The gallery interface 1110 may include one or more albums (e.g., all photo albums, favorites albums, camera albums, screen capture catalog albums, travel albums 1111, microblog albums, etc.). Each photo album may include one or more pictures. For example, the travel photo album 1111 may include 2 pictures therein.

The electronic apparatus 100 may receive an input operation (e.g., long press) by the user with respect to the travel album 1111, and in response to the input operation, the electronic apparatus 100 may display the function window 1120 as shown in fig. 11B. The pictures included in the travel photo album 1111 may be stored on the cloud server and bound to the cloud account a.

Only the sharing party (cloud account a) of the travel album 1111 can obtain the information currently, and therefore the album member list includes the identifier 1131 corresponding to the cloud account a. The current photo album to be shared is the travel photo album 1111, so the list of the photo albums to be shared includes the identifier 1133 corresponding to the travel photo album 1111. The album member add control 1132 may be used to add an account for obtaining the album to be shared. The photo album 1134 to be shared may be used to add a photo album to be shared. Each photo album to be shared comprises one or more pictures. The publicly shared album control 1135 may be used to open or close the publicly selected album. Currently, the publicly shared album control 1135 is in a closed state. The album address send control 1136 may be used to trigger the electronic device 100 to send the acquired address of the selected album to other devices.

The electronic device 100 may receive an input operation (e.g., a single click) from a user with respect to the publicly-shared album control 1135, and in response to the input operation, the electronic device 100 may open the function of the publicly-shared album.

As shown in fig. 11D, the electronic device 100 has opened the public sharing album function, and the public sharing album control 1135 is in an open state. The electronic device 100 may display the two-dimensional code 1137 on the album sharing interface 1130. The two-dimensional code 1137 may be used for scanning by other devices, so that the other devices acquire the acquisition address corresponding to the travel album 1133.

The user name of the cloud account a logged in on the electronic device 100 may be "Daniel", the cloud account B may be logged in on the electronic device 101, and the user name of the cloud account B may be "MAC".

The electronic device 101 may obtain the album (or the picture) shared by the electronic device 100 through the cloud account a by: 1. the electronic device 101 may obtain an obtaining address of an album (e.g., the travel album 1111) to be shared by the electronic device 100 by scanning the two-dimensional code 1137 of the album sharing interface 1130 shown in fig. 11D. 2. The electronic device 100 may receive and respond to the input operation with respect to the album address transmission control 1136 shown in fig. 11C, and transmit the acquired address of the album to be shared (e.g., the travel album 1111) to the electronic device 101 through a social application or the like. 3. The electronic device 100 may add the cloud account B corresponding to the electronic device 101 to the album member list, and send the acquired address of the album to be shared (e.g., the travel album 1111) to the electronic device 101 logged in with the cloud account B through the cloud server.

For example, as shown in fig. 11E, the electronic device 100 may add the cloud account B corresponding to the electronic device 101 to the album member list. The album member list may display an identifier 1131 corresponding to the cloud account a logged in on the electronic device 100 and an identifier 1138 corresponding to the cloud account B logged in on the electronic device 101. The electronic device 100 may send an acquisition address of an album (e.g., the travel album 1111) to be shared to the electronic device 101 logged in with the cloud account B through the cloud server.

After receiving the acquisition address of the album to be shared (e.g., the travel album 1111), the electronic device 101 may send an album acquisition request to the cloud server according to the acquisition address. After receiving the acquisition address of the album to be shared (e.g., the travel album 1111), the cloud server may send the thumbnail corresponding to each picture included in the album to be shared (e.g., the travel album 1111) to the electronic device 101.

Illustratively, as shown in fig. 12A, the electronic device 101 may be displayed with a cloud album interface 1210. The cloud album interface 1210 displays thumbnails (e.g., thumbnail 1211 and thumbnail 1212) of picture files included in an album (e.g., the travel album 1111) to be shared by the electronic device 100.

The electronic device 101 may receive an input operation of a user for the thumbnail 1211, and in response to the input operation, the electronic device 101 may acquire an acquisition address of the thumbnail 1211 corresponding to the picture file and download the picture file from the cloud server to the local according to the acquisition address of the picture file. The cloud server may send the picture file to the electronic device 101 after encrypting the privacy information in the Exif data in the picture file.

For example, as shown in fig. 12B, the electronic device 101 may receive and respond to an input operation (e.g., a single click) of the thumbnail 1211 by a user, and obtain a picture file corresponding to the thumbnail 1211 from the cloud server. After acquiring the picture file corresponding to the thumbnail 1211, the electronic device 101 may store the picture file in a cache, acquire non-private information in the main image data and the Exif data from the picture file, and display a picture 1221.

In some embodiments, the electronic device 100 may specify that some other users' devices are authorized to obtain the private information in the shared picture. Specifically, the electronic device 100 may send a device identifier (e.g., a cloud account ID) that has a right to acquire the private information in the picture file to the cloud server. After receiving a picture acquisition request for the picture file a sent by the electronic device 101 (with the cloud account B logged in), the cloud server may determine whether the electronic device 101 has the authority to acquire the privacy information in the picture file according to a device identifier (for example, a cloud account ID) of the electronic device 101. If the image file has the authority, the cloud server may send the image file a with the encrypted private information and the encryption key to the electronic device 101. If the authority does not exist, the cloud server may send the picture file a with the encrypted privacy information to the electronic device 101. In this way, the electronic device 100 may enable different recipients to set different picture file obtaining permissions, and may enable devices of the recipients (e.g., relatives, coworkers, etc.) specified by the user to obtain the privacy information in the shared picture file, and devices of other recipients (e.g., strangers) may not obtain the privacy information in the shared picture file, thereby protecting the privacy of the user

In one possible implementation manner, the electronic device 100 may encrypt the private information in the local picture, and then send the picture data after encrypting the private information and the key to the cloud server. When the electronic device 100 wants to share a picture with other devices, the electronic device 100 may send an identifier of a device that has a right to acquire privacy information in the picture to be shared to the cloud server. When the cloud server receives a request for obtaining a picture to be shared, which is sent by another device (e.g., the electronic device 101), the cloud server may determine, according to a device identifier (e.g., a cloud account) of the other device (e.g., the electronic device 101), whether the other device (e.g., the electronic device 101) has a right to obtain privacy information of the picture to be shared. If another device (e.g., the electronic device 101) has permission to acquire the privacy information of the picture to be shared, the cloud server may send the picture to be shared and the key after encrypting the privacy information to the other device (e.g., the electronic device 101). If the other device does not have the right to acquire the privacy information of the picture to be shared, the cloud server may send the picture to be shared after encrypting the privacy information to the other device (for example, the electronic device 101).

In some embodiments, if an application a (e.g., a cloud album application) has permission to access privacy information of a picture on the electronic device 100, after determining a receiving device (e.g., the electronic device 101 logged in a cloud account B) of the picture to be shared, the electronic device 100 may determine whether avatar information of an account (e.g., the cloud account B) on the receiving device (e.g., the electronic device 101) is included in the picture to be shared. That is, the electronic device 100 may determine whether the picture to be shared includes the avatar of the account setup on the receiving device. When the avatar information corresponding to the account on the receiving device (e.g., the electronic device 101) is included in the picture to be shared, the electronic device 100 may send the picture to be shared to the receiving device (e.g., the electronic device 101) through the application a. When the avatar information corresponding to the account on the receiving device (e.g., the electronic device 101) is not included in the picture to be shared, the electronic device 100 may delete the privacy information in the picture to be shared, and then send the picture to be shared after the privacy information is deleted to the receiving device through the application a. Therefore, only the receiver of the account avatar in the picture can acquire the privacy information in the picture, and the privacy of the user is protected.

In one possible implementation manner, when avatar information corresponding to an account on a receiving device (e.g., the electronic device 101) is included in a picture to be shared, the electronic device 100 may send the picture to be shared with encrypted privacy information and a key for decryption to a second electronic device through the application a. When the avatar information corresponding to the account on the receiving device (e.g., the electronic device 101) is not included in the picture to be shared, the electronic device 100 may send the picture to be shared, which is encrypted with the privacy information, to the receiving device (e.g., the electronic device 101) through the application a.

In some embodiments, the electronic device 100 may upload the local picture files to the cloud server for storage through an application a (e.g., a cloud photo album application). The electronic device 100 may browse the picture file saved in the storage space of the cloud account a on the cloud server by logging in the cloud account a on the application a. The electronic device 100 may share the picture to be shared selected by the user on the cloud server to the device corresponding to the other cloud account. The cloud server may determine whether avatar information of a cloud account logged in a receiving device (e.g., the electronic device 101) requesting to acquire the picture to be shared is included in the picture to be shared. If so, the cloud server may send the picture to be shared to a receiving device (e.g., the electronic device 101). If not, the cloud server may delete the privacy information in the picture to be shared, and then send the picture to be shared after deleting the privacy information to the receiving device (e.g., the electronic device 101). Therefore, only the receiver of the account avatar in the picture can acquire the privacy information in the picture, and the privacy of the user is protected.

In some possible implementations, when avatar information corresponding to an account on a receiving device (e.g., the electronic device 101) is included in the picture to be shared, the cloud server may send the picture to be shared with the encrypted privacy information and the key for decryption to the second electronic device. When the avatar information corresponding to the account on the receiving device (e.g., the electronic device 101) is not included in the picture to be shared, the cloud server may send the picture to be shared after encrypting the privacy information to the receiving device (e.g., the electronic device 101).
